I wrote this to another poster in another thread

I have extensive expreience in this area...as I have both Electrical (licensed) and Low Voltage (even more experience, but no licnesing in CO yet)...

I would suggest, in a friendly way...that you re-read this section of the NEC, as it clearly defines the rules for this...

If you contact any of the manufacturers I mention here (which I had to do to win a deabte with one inspector) they will supply you with extensive amounts of information pertainig to this issue!

Further...almost ALL NC and Retro Boxes made today that are more than one gang, have seperating fins mentioned by the NEC installed on them...so not only are all of these devices maintaining the minimum .25 inch clearance, they are ALSO including a hard seperator...

Submssions to the NEC does nothing for me, or most of the people here....anyone can submit anything to anyone!

"You are mistaken. The NEC DOES allow LV and 120VAC in the same box...there is a minimum seperation required of I believe .25 inch from the LV and the Line Voltage, but they are absolutely allowed in the same box when neccesary. Reading your profile, I see you're from California, so that could be the confusion. CA, or your municipality, may have a code against it, but the NEC does not prohibit it, just has minimum distances that must be adhered to.

Examples would be as follows:

Lutron Graffik Eyes
PHAST, AMX and Panja light switches
Some Lutron Devices
Some Litetouch Devices
Some Vantage Devices
Some Crestron Devices
Some Leviton Devices
CasaBlanca Ceiling Fans
Heatilator Fireplaces
Stewart, Draper, Da-Lite Film Screens controllers
etc...

All of these have LV control point right next to line voltage feeds, in the same box.
